BY EFFECTIVE PLANNING, SCHEDULING AND CONTROLING.
Implementation of reliability centred maintenace to manufacturing equipment so as to reduce delay and wastages associated to equipment failure, and ensuring optimal spare availability through effective inventory control as well as human factor management.
an introduction
Waste reduction policy is one of the most (or most) successful and successful manufacturing management systems in the world. This system was introduced by the Japanese Toyota Motor Company (known car company) in the 1970s (ie, about 40 years ago) and showed remarkable results. In the 1980s American and European companies began to be surprised by the superiority of Japanese companies as a result of the application of this system and therefore began to try to understand this policy and try to apply it. To date, this policy still outperforms any other policy of manufacturing management and even service management. Toyota continues to be the ideal model for managing production operations in the world and its success continues. In this article, I attempt to introduce a policy of reducing waste so that we can understand and apply it.
what is it?
The policy of reducing waste aims to reduce the losses in all production processes. This policy is characterized by helping us get rid of many of the losses that are usually considered inevitable. Many consider the time of stomach control as normal and we have to live with it, as well as inventory and equipment failures and waiting times and times Transportation. The policy of reducing waste enables us to reduce these losses dramatically and make the production process very efficient. This policy (system) is called several names in English
Just In time Any production is timely and timely stock compensation is one of the most famous designations and abbreviated to JIT
Lean Production Any thin production that is not overloaded or overworked or other losses
Lean Manufacturing Any slim manufacturing
Toyota System or Toyota Production System Any Toyota system or Toyota production system relative to the origin of this policy at Toyota. Abbreviated to TPS.
But all these names mean the same policy and aim for a clear goal is to reduce (waste) Waste Elimination and I think this is the common name in Arabic is better than others because they illustrate the reality of this policy. Even the name Just in Time makes many people think that this policy means - just - there is no stock at all and this is a big mistake. This policy is not only aimed at reducing inventory, but is aimed at reducing waste, and it is the stock that can be dispensed with. It also does not make inventory zero but makes inventory very little compared to companies that do not apply this policy.
You may find that some deal with JIT as part of the TPS and this in turn is part of Lean Manufacturing. This is of little concern to us in our discussion of the policy of reducing waste. We want to know all the details of this policy, whether it is called TPS, JIT or Lean.
The policy of reducing waste is a system consisting of several systems (elements) all designed to reduce losses. These systems interact with each other to give us the successful impact of the loss reduction policy. JIT is not just a method of inventory management or production planning but a culture, philosophy and a set of mutually supportive systems.
Ship reduce waste
The policy of reducing waste was not applied and developed at a specific moment but was developed in Japan after the Second World War in about twenty years and dates back to pre-World War II. During the development of this policy the need arose for these different systems to complement each other. For example, you can not reduce inventory without reducing the proportion of defective products and you can not apply the policy of withdrawal of production without reducing the time of equipment and equipment malfunctions.
Some believe that the policy of waste reduction or JIT aims to reduce the stock simply because the stock represents a financial value is not invested, but cost us the cost of storage. It's much deeper. The policy of reducing waste looks at the stock as a fundamental reason for the existence of many losses. The large stock makes us overlook (or not see) many problems while the lack of stock make us keen to solve these problems and thus get rid of losses. A very famous example explains this idea
